This article looks at latest trends in radiation detection and at the growing sophistication of the equipment designed to uncover radioactive sources in scrap metal and other material ...

  • Instrument selection and use for measurements in a radiological emergency

    A discussion of monitoring during a radiological emergency response is presented. This paper focuses on a response for the USA, but many principles would also apply for other countries. This paper starts with a discussion on instrument selection and preparation. Different scenarios based on materials involved and responder levels are presented with equipment concerns for each. This paper ...

  • Present Status and Future of Advanced Scientific Instrument using X-ray

    X-rays have attracted a lot of attention as a form of electromagnetic radiation that enable us to see objects through materials. And they are also a great contributor to clacification of physical phenomena. In the field of analysis, X-rays have drawn attention from their initial stage as a method of non-destructive simultaneous anaysis. Scientific measurement using X-rays is supported by three ...

  • Studies on natural radioactivity of some Egyptian organic and chemical fertilisers

    Radiometry techniques were applied to evaluate the activity and concentration values of 238U, 232Th and 40K in four types of Egyptian made fertilisers. Also, radon and thoron concentration values were estimated for the same samples. The Hyper-Pure Germanium Detection System (HPGeDS) installed at the hot laboratories of Inchas, Cairo, and the Solid State Nuclear Track Detection System (SSNTDS) ...

  • Aerial radiological systems, measurements and analysis

    This document describes data collection systems and procedures used by the US Department of Energy Aerial Measuring System (AMS) in response to a radiological emergency. The discussion is split into two parts: (1) those systems used on the fixed-wing aircraft and (2) those systems used on the helicopters. This split is principally caused by the final use of the data from each system. The ...

  • Urban wastewater reuse: a pilot plant experience

    The results of a preliminary verification of domestic wastewater reusability in L'Aquila (Italy) are reported. A Tertiary Treatment Pilot Plant (TTPP), rotary filtration and Ultraviolet (UV) Radiation disinfection, was added to an Urban WasteWater Treatment Plant (UWWTP) to test the compliance with water quality indicated for reuse by the enforced Italian regulation. The TTPP was managed varying ...

  • Nuclear Applications using CO₂ Sensors

    Safety is a top priority for nuclear applications in power plants. CO₂-cooled reactors are inherently safer than water-cooled reactors, but it is essential to prevent, detect, and repair CO₂ leaks to maintain safe operation. Infrared sensors from Edinburgh Sensors provide the ideal leak detection solution for nuclear research and nuclear power plants. Nuclear power stations convert energy stored ...

  • Improvement of epidemiological data analysis by unbiased estimates of log-normal dose distribution

    The effects of radiation on population and risk assessment are studied through epidemiological studies that are heavily dependent on dose distribution. Radiation doses to individual workers follow a log-normal distribution. Computation of the collective dose with the minimum detectable values (Detection Limit or DL) as zero is biased. Hence the expectation value of the 'missed' doses is computed ...

  • STS Supply more DP6 simulators

    STS have received further orders for our unique training simulator for the Thermo RadEye(tm) SX. The latest orders come from the European Commission Joint Research Centre's Nuclear Safeguards & Forensics section and adds to their existing suite of contamination and radiation simulation systems from STS. ...

  • STS appoints Korean Distributor

    STS is very pleased to announce that it has appointed its first distributor in South Korea. Si Detection are part of the Satrec Initiiative group who specialise in radiation monitoring equipment and satellite technology. Mr Terry Lim of Si Detection approached STS concerning distribution of the STS range of Contamination simulators and Field Survey simulators in Korea. STS have now provided Si ...

  • Chromosomal aberrations in Iranian radiation workers due to chronic exposure of X-irradiation

    The frequency of chromosomal aberrations in the peripheral blood lymphocytes of 65 radiology technologists working in hospitals in Tehran, Iran, who had been chronically exposed to X-rays, was analysed. Although film dosimetery did not show the maximal annual permitted dose (20 mSv per year) in any of the examined subjects, cytogenetic analysis detected fairly high levels of chromosomal ...

  • Evaluation of detection abilities of monitoring networks using multiple assessment criteria

    The problem of evaluation of radiation monitoring network quality is considered. The comparison of possible network configurations is performed on simulated experiments where a twin model is used to simulate observed data. An assimilation procedure based on the particle filter approach is run for each configuration of the network. Specifically, multiple realisations of segmented Gaussian plume ...

  • Atmospheric dispersion of argon-41 from a nuclear research reactor: measurement and modelling of plume geometry and gamma radiation field

    An atmospheric dispersion experiment was conducted using a visible tracer along with the routine releases of 41Ar from the BR1 research reactor in Mol, Belgium. Simultaneous measurements of plume geometry and radiation field from 41Ar decay were performed as well as measurements of the 41Ar source term and the meteorological parameters. ...

  • The development of radiobiology in Bulgaria

    The ongoing changes in radiation risk assessment and development of ICRP conceptions is greatly due to the achievements of radiobiology. At doses below 0.2 Sv, radiation risk is determined only by stochastic effects. In these cases initial changes at molecular and cellular level and potentially lethal damage cannot be detected with known methods. Radiobiology and molecular epidemiology will ...

  • A meta-level true random number generator

    True random number generators (TRNGs) are extensively used in cryptography, simulations and statistics. In this work, we introduce, extend and analyse the concept of the randomised bit cell (RBC), introducing a second meta-level of randomisation, being able to simultaneously produce random numbers and detect active non-intrusive attacks. The concept is extended by using a corrector. ...

  • National system for prevention of nuclear and radiological terrorism in Lithuania

    Minimisation of the threat posed by nuclear and radiological terrorism and mitigation of its impact is one of the most important tasks for any state. Prevention of the diversion of nuclear and radioactive material is related to a number of measures, which include the physical protection of the nuclear industry, readiness for investigation of the appropriate incidents and accidents, emergency ...

  • Unusual long-lasting effects induced by low doses of radiation: electron microscopy studies of endothelium of rat myocardium capillaries

    An attempt is made to substantiate experimentally the pathophysiological mechanism of disturbance in relatively radio-resistant tissues (myocardial capillary endothelium of rats) after X-ray irradiation at low doses comparable with doses to liquidators of the Chernobyl accident. It has been found that the X-ray radiation at a dose of 0.5 Gy induces long-lasting potential alterations in rat ...
